Abstract: 590,269. Mountings for non - recoil guns. BURNEY, SIR C. D. Oct. 23, 1942, No. 14889. [Classes 92 (i) and 92 (ii)] A mobile high-angle non-recoil gun of the kind described in Specification 586,749, has a breech chamber 9 behind the projectile communicating through a bridgepiece 19 with a pair of rearwardlydirected gas-discharge nozzles 10, the gun being mounted by rear trunnions x, off-set from the training axis, on the cheeks 6 of a turntable or turret 5 which can be traversed on a frame 1 supported on wheels 2, 3. The arrangement is such that the discharge from the nozzles, when the gun is elevated, is clear of the vehicle frame in substantially all positions of gun traverse. The projectile is loaded fowardly into the chamber 9 by using a ram-rod 17 and loading tray. The cartridges are inserted rearwardly into chambers 8 from a loading platform 11 mounted on pivoted links 12 to rise and fall with the gun during its elevational movements. The mounting is transported, after depressing the gun barrel on to the frame 1, by connecting the limber vehicle to the axle of the wheels 3.

Filed: 1945-06-12
Abstract: 593,725. Snap-action switches. OLSSON, G. D. June 12, 1945, Nos. 14925 and 14926. Convention dates, July 11, 1944, and May 16, 1945. [Class 38(v)] A push-button 11 actuates a rotatable contact-carrying body 3 by means of a spring 14 which stores energy until the resistance of resilient stationary contacts 16 is overcome. After switching, the button 11 is restored by a helical spring 31 whilst the spring 14 retires behind the next tooth of a ratchet wheel 12 secured to the body 3, which carries contacting and insulating surfaces in camming engagement with the contacts 16. In a modification, Fig. 7, a second helical spring 42 stores and transmits energy for the actuation of the body, Fig. 11, by a spring 43. This spring 43 does not move until a plate 44 secured to it is struck by a central projection 28 of the button 11. A conductive sleeve 49 may connect one contact strip having surfaces 48, 50 with a similar coaxial contact strip also secured to the body 3 and thereby forming a change-over switch. The invention may be applied to multi-pole switches.

Filed: 1926-06-15
Abstract: 277,733. Mitchell, H. C. June 15, 1926. Ornamenting.-Paper or other surfaces suitable for window tickets and show cards are prepared for writing or other impressions, as with a dry pen, by giving the surface a coating similar to that of an art coated paper. such as is obtained by the use of china clay and blanc fixe, and then applying ink or colour to the surface so that moisture is accessible to the surface upon which the ink or colour is applied. The colour or ink may be applied by means of a. half-tone print. A style such as the reversed end of a pen nib may be used for writing; the act of writing removes the ink or colour and exposes the under surface. Any adhering substances may he removed by a sponge.

Abstract: 1434888 Skylight; window fastenings K GOBEL 4 April 1974 [21 April 1973 14 March 1974] 15087/74 Headings E1J and E2A [Also in Division A5] A skylight 2 is pivoted about horizontal pivots 4 at one end of each of two parallel, horizontal rails 3 which are longitudinally slidable in guides 10 secured to a support frame 1 the skylight overlying the rails and guides when closed. The rail and guide are each channel sectioned, the rail having a roller 8 at one end acting on the guide and the guide carrying a roller 14 acting on the rail. A spring 9 acts between the rail and guide to bias the skylight to slide to an open position. A flange 18 on the skylight carries a roller 19 co-acting with an end 16 of the guide to prevent the spring causing such sliding until the skylight has been pivoted to a partially open position. The skylight has a detent 21 which is engageable in a pawl 24 which is biassed upwardly (e.g. by pneumatic cylinder 30 or a spring) so as to urge the skylight to an open position. The pawl can be held in a lowered, locking position (shown in dashed lines in Fig. 6) by means of a pivotal lever 33 which, when held horizontally, has a catch 36 which prevents the pawl from moving upwardly. The lever 33 is held horizontally by a hollow body 39 engaged between it and a horizontal block 37. The block 37 is pivotal about 38 to release the lock, but it can be held in its horizontal, locking position by a lever 40 for engaging an electromagnetically operable catch 42. The 'body 39 is designed to shatter upon a threshold temperature (e.g. 60C) being exceeded to thereby automatically unlock the skylight.

Title: Improvements in and relating to the coating of surfaces of materials with layers of gallium, germanium or indium or alloys consisting of two or all of these metals
IPC: H01B1/00
Filed: 1955-06-01
Abstract: 769,825. Coating with metals; germanium alloy. FRANCAIS, ETAT. June 1, 1955 [Dec. 31, 1954], No. 15677/55. Classes 82(1) and 82(2) In a process for coating the surfaces of materials, such as metals, graphite, quartz and ceramics, with gallium, germanium, indium or alloys consisting of two or all of these metals, vapour of the monoxide of the coating metal is condensed on the surface to be coated and the monoxide is reduced to the metal. The surface to be coated is placed in the apparatus which serves for the preparation of the monoxide and this preparation is preferably performed by heating, at a temperature higher than 600‹C. and under a pressure of less than 1 atmosphere, in carbon dioxide mixed with carbon monoxide, the metal, the normal oxide of the metal, alloys containing the metal, or a mixture of the metal and its normal oxide. Referring to the Figure, the plate 5 to be coated is placed in its housing 6 opposite the end of the nozzle 4, which is formed in the quartz tube 1. The material to be converted into monoxide is placed in the cupel 3 and then heated by the electric furnace 2 to a temperature of between 700‹ and 1000‹C.; the vacuum pump 13 is started and draws a mixture of carbon dioxide and carbon monoxide from the reservoir 11 into tube 1 where the subsequent reaction produces the monoxide which condenses on to plate 5, which is kept by the cooler 7 at a temperature of between 400‹ and 500‹C. When sufficient monoxide has been deposited, vacuum pump 13, reservoir 11 and cupel 3 are withdrawn and a current of hydrogen is passed through the apparatus to convert the monoxide into the metal. During the reduction the temperature of the plate is preferably 500‹ to 600‹C. In an example is described the production of a layer of germanium containing 0.1 per cent of indium on a quartz plate, by utilizing for the production of the monoxide a mixture of germanium oxide, GeO 2 , and indium oxide In 2 O 3 , a furnace temperature of 950‹C., a temperature of the quartz plate of 450‹C., a 50/50 mixture of carbon dioxide and carbon monoxide, a pressure of 10 mm. of mercury and a time of 20 minutes, and for the reduction of the monoxide by hydrogen a quartz plate and furnace temperature of 600‹C., atmospheric pressure and a time of 30 minutes. The process is said to be useful for the manufacture of transistors and photovoltaic cells.
